Patent GB-2258323-A (GB)
Title: Apparatus for supplying pulsed compressed air
Inventor: BOSTOCK-SMITH DAVID
IPC: B05B12/06
Filed: 1991-07-03
Abstract: A device for providing a pulsed stream of compressed gas or fluid has a barrel (1) for connection at one end to a supply of compressed gas or fluid, a nozzle (7) being provided at the other end. A cylinder (12) is provided in the barrel (1), passageways (13) extending outside the cylinder (12) to allow fluid to pass within the barrel from inlet to nozzle. Slidable within the cylinder is a plunger (23), the cylinder and plunger having a stepped cross section and a projecting portion (26) for closing the nozzle in one position. A pressure (21) passageway extends into the cylinder (12) adjacent the nozzle end, and a bleed (20) to atmosphere further up the cylinder (12). The plunger is hollow, and the effect is that when the projecting portion of the plunger closes the nozzle, compressed fluid forces the plunger out of engagement with the nozzle, and when the plunger is out of engagement with the nozzle, the plunger is forced by fluid pressure towards the nozzle, leading to a reciprocating motion and pulsed air flow. The frequency of oscillation is a function of pressure, the mass of the plunger, the cross-sectional areas of the various passages and channels, and the leakage paths between the various chambers and the cross-sectional areas present at the discontinuities in the plunger. <IMAGE>
